SPRAY NOZZLE.

'Original application illed August 17, 1922, Serial No. 582,396. Divided and this application filed July v 30, 1923. Serial No. 654,520.

This invention relates lto spray nozzles and aims to provide for even distribution over a lconsiderable area of a fluid suppliedat a slow'rateand under a low pressure. A' "further objectof the invention is to provide such a nozzle in a form that may be constructed at small cost.

In accordance with the invention, a nozzle is provided with a discharge slit and with deflecting means located near the ends of the slit and arranged to cause two streams of the fluid to impinge against each other just inside the slit. It has been found that such a nozzle projects a thin fan-like shaped spray through its discharge slit even when the fluid is supplied in small quantity and under low pressure.

While a nozzle embodying the invention is useful for man purposes, the nature ofI the invention mayI be understood from a detailed description of in illustrative nozzle forming part of a dishv washingmachine which is described and claimed plication tiled August 17,

582,396, of which this application is a division. Such a nozzleis shown in the accompanying drawing which is an enlarged side View. of the nozzle partly sectioned on the plane ,of its discharge slot.` v

The. nozzle R15, which) 's mounted on a supply pipe R1 over a'later'al opening therein, has a general conical giorni and is provided at its upper end-with a short diametrical discharge slit R16. The' material of vthenozzle is pressed in atfeach end of the slit R16, so as to -form an inwardly projeotingfw deflector R17 just-inside each end of the slit.l The fluid iiowing outwardly along opposite walls of the nozzle is directed in- 1922, Serial No.

in my co-pending ap-l Wardly by the detlectors R17 so lthat two streams of the fluid impinge against each other just inside the slit R16. This has been found to result in projecting the 4lluid through the slit in the form of a very thin, fan-like spray.

The discharge may extend longitudinally of the supply pipe R1 is shown. The nozzle R15 is stamped from a piece of metal and is provided with a cylindrically curved ilange which may be sweated or otherwise secured tothe pipe R1.

What is claimed is:

1. A spray nozzle having a general conical shape and provided with a diametrical slit across its apex and with deflecting surfaces inclined inwardly from its conical wall just inside the ends ofthe slit.

2. A spray nozzle comprising a hollow body having adischarge slit,` and means for causing two streams of iluid to move in opposite directions longitudinal of the slit and to impinge against eachother within the hollow body and just inside said slit.

3. A spray nozzle comprising a hollow body which decreases in cross-section toward itsouter end, has a transverse slit across its outer end, and deflecting surfaces inclined inwardly fromv its inner'wall just inside the ends of the slit.

4. A spray nozzle, comprising a hollow body which decreases in cross-section toward itsA outer end, is provided with a transverse slit across its outer end, and has portions bent inwardly from its conical wall at the ends of the slit.

In testimony whereof I have hereunto set my hand.
